Regulations of China Municipality on Meteorological Work:

Light rain (rainfall)

(1) 1 hour rain with rainfall less than or equal to 2.5 mm;

(2) Rain with rainfall less than 10mm within 24 hours.

Rainfall grade

Rain is divided into light rain, light rain, moderate rain, heavy rain and heavy rain. These grades are clearly defined.

Light rain: It means that the rainfall is less than 0. 1mm within 24 hours, commonly known as "Mao Mao rain".

Light rain: within 24 hours, the rainfall is 0. 1 to 10 mm, which can wet clothes. There was a little water on the road, and the mud was all wet, but there was no water.

Moderate rain: within 24 hours, the rainfall 10 to 25mm, the sound of rain can be heard, and there is a small amount of water in the depression.

Heavy rain: within 24 hours, the rainfall is 25-50 mm, the sound of rain is fierce, and the ditch flows rapidly.

Heavy rain: refers to a large amount of precipitation within 24 hours, with rainfall greater than 50 mm.

Heavy rain: within 24 hours, the rainfall reaches 100 mm or more.

Heavy rain: the rainfall exceeds 200mm in 24 hours.

Shower: This kind of rain will suddenly start and stop. The most urgent time of rainfall is very short, and the intensity changes dramatically.

Therefore, the name of the shower is determined by the nature of rainfall rather than precipitation, and the amount of decline may sometimes be small. Rain mainly comes from cumulonimbus clouds, sometimes accompanied by thunderstorms.
